Wireless Phone Number Finder
To identify the carrier that supplies service to a phone customer and their location, visit these sites and enter your Area Code and Prefix (NPA-NXX). Some numbers may no longer conform to these records after having been "ported" through Local Number Portability. In those cases, only the original assignment is shown. Some old cellular company names are shown as that is how they are still listed in the administrator's records. To find what is Local to your phone, check the "Local Calling Guide."

  • NANPA
    The official Area Code & Prefix-assigning organization. Choose a state and you get all Prefixes for that state and Area Code, wireless and wireline. The results are large files.


  • TELCO DATA
    A frequently-updated and easy-to-use site. Enter your Area Code and Prefix and get a result of the name of the carrier that was originally assigned that Prefix.


  • FONE FINDER
    Enter the first 6 or 7 digits to get a result. The site includes Canadian and other international numbers.


  • LOCAL CALLING GUIDE
    A database that provides a cross-reference among switches and local calling areas which can be tailored with a small or great amount of detail. We use this site to find what exchanges are 'Local' to a particular cell phone number. It also refers back to the NANPA database.
